After having completely avoided the area for over two hours, in a part of town where police can be seen rolling by regularly -- and this despite the street party fully blocking traffic at 23rd & Telegraph, then Telegraph and Grand, and back again at 23rd -- Oakland police were on the scene in a matter of minutes following the attack. The Gender Rebel street party and the Art Murmur crowd largely dissipated of their own volition once police arrived. Heard numerous times amongst those remaining, as people tried to process the brutality of what had just happened seemingly out of the blue, was that the many-on-one attack was too sudden and too methodical to be some random street brawl. The feeling amongst witnesses to the beating was that the attackers who appeared out of nowhere -- actually coming directly out of the "Para Diso" bar at 2272 Telegraph to attack a single person in the middle of the crowd -- were actually provocateurs allied with law enforcement, sent to scare off the crowd by the sight of bodily violence and to offer a pretense for police to finally move in and disperse the crowd.
